Chapter 6, Problem 6B.3DQ

Interpretation Introduction

Interpretation: The molecular basis of Van’t Hoff equation for the temperature dependence of $K$ has to be explained.

Concept introduction: Van’t Hoff equation expresses the relation between enthalpy of reaction and equilibrium constant.  It also relates the change in equilibrium constant with change in temperature.  The Van’t Hoff equation is expressed as,

  $\frac{d\ln K}{dT}=\frac{{\Delta }_r{H}^{\text{ο}}}{R{T}^2}$
